ZThis invention relates to machines for candy making, and, more particularly to the type designed to produce shells, tubes, or

ackets,hereinafter called shells, from chocolate liquid orpaste, or other'suitable material,

adaptable for laterfilling with cream, fruit I jelly, and what not. i i

' 'It'has for its objects to provide an efiicient and inexpensive manufacturing equipment '1 fo'r forming or casting liquid, paste, or dry .material," into shells'and for removing same when set, hardened, or finished, said equipment adaptable for gang or multiple unit as- ;sembly, to increase production wi h minimumlhelpyto reduce production cost; to insure uniformity in product; and to provide the var ous other advantages and results ifmade' evident from the following specifications w I accomplish the objects of invention as shown in the accompanying drawings, whichform a part of this specification and inv which similar letters of reference refer to similar parts throughout thegvarious views.

The mechanism comprisesa body form mould holding plate immovably fixed upon parallel uprights. "A stripper plate slidably mounted upon said uprights just, below said body form plate and adaptable to hold ,the finished shells within the moulds in said body form plate" when the inside formers on'the inside former plate, hereinafter referred to,

are withdrawn, an inside former plate, with inside formers thereon,slidably mounted on said, uprights immediately beneath said stripper plate, a thermal chamberor heater 'plate hereinafter called, heater plate, also slidablyfmounted' on said uprights, below said inside former plate, a tableplateslidably 'mounted on said uprights, beneath said heater plate and equipped with lifting'and lowering means, hydraulic or otherwise, a punch plate or "shell remover, with punches mounted thereon, slidably mounted on said uprights above said body form plate and also equipped with "lifting and lowering means similar to that on said; table plate, and a basket adaptable to catch said shells as they are forced out of the moulds in saidbody form plate by lowering the punches and punch plate after thestripper and other parts beneath are inlowered position soas to provide room for the basket to be inserted under the body form plate.

In the drawings, Figure 1 shows a front view of the machine in gang. form with the finished shells dropped from the moulds into the receiving basket whichbasket is convenientl held in position on the machine by projectmg fingers thereon which engage grooves in the body form plate. Figure 2 shows a sectional frontview of the machine with the inside former plate, stripper plate, heating plate and table plate all in raisedposition..

of contact and the substance from which the shell is composed in position within said shell moulds in said body form plate and about the inside formers. Figure 3 is a sectional front view similar to Figure 2 with the strip--,.

per plate in position of contact below the body form plate, the inside former plate, the heater plate and the table plate being in lowered position preparatory to removing the finished shells from the body form plate.,.

This view shows the function of the stripper plate inholding the shells withinthebody forms while the inside former plate is being lowered, Figure 4 shows a sectional front view with the stripper plate,inside former with the body moulds in the body form plate so asto allow passing of the punches therethrough. Figure 6 shows the gate'valve plate in position sealing the top of the moulds in the body form plate, the stripper plate, inside former, heater plate and table plate being in positions of contact, by force of which the tablet, of predetermined size, is pressed and moulded to the shell shape desired. Figure 7 manner the exact temperature desired for the parts is securedifor improved results in creating and handlingthe product at various stages of manufacture.
